Atlas V is an active expendable launch system in the Atlas rocket family. Atlas V was formerly operated by Lockheed Martin, and is now operated by the Lockheed Martin-Boeing joint venture United Launch Alliance. Each Atlas V rocket uses a Russian-built RD-180 engine burning kerosene and liquid oxygen to power its first stage and an American-built RL10 engine burning liquid hydrogen and liquid oxygen to power its Centaur upper stage. The RD-180 engines are provided by RD AMROSS, while Aerojet Rocketdyne provides both the RL10 engines and the strap-on booster rockets used in some configurations. The standard payload fairing sizes are 4 or 5 meters in diameter and of various lengths, and are made by RUAG Space. Fairings sizes as large as 7.2 m in diameter and up to 32.3 m in length have been considered.[3] The rocket is assembled in Decatur, Alabama; Harlingen, Texas; San Diego, California; and at United Launch Alliance's headquarters near Denver, Colorado.[4]

In its more than three dozen launches, starting with its maiden launch in August 2002, Atlas V has had a near-perfect success rate. One flight on June 15, 2007, NRO L-30, experienced an upper-stage anomaly when the engine in the vehicle's Centaur upper stage shut down four seconds early, leaving the payload—a pair of naval signals intelligence satellites—in a lower than intended orbit. However, the customer, the National Reconnaissance Office, categorized the mission as a success.[5][6]

On May 13, 2014, Russian Deputy Prime Minister Dmitry Rogozin announced that Russia would no longer supply rocket engines for U.S. military launches, amid tensions arising from the 2014 Russian military intervention in Ukraine. United Launch Alliance has a two year supply of engines, enough for scheduled launches and permitting a transition to the Delta rocket family, which uses only U.S. produced engines.[7]

History[edit]

The Atlas V is the newest member of the Atlas family. Compared to the Atlas III vehicle, there are numerous changes. Compared to the Atlas II, it is a near-redesign. There was no Atlas IV.

  1. The "1.5 staging" technique was dropped on the Atlas III, in favor of a more-advanced RD-180 engine.[8] The RD-180 features a dual-combustion chamber, dual-nozzle design and is fueled by a kerosene/liquid oxygen mixture.
  2. The main-stage diameter increased from 10 feet to 12.5 feet. As with the Atlas III, the different mixture ratio of the engine called for a larger oxygen tank (relative to the fuel tank) compared to Western engines and stages.[citation needed]
  3. The first stage tanks no longer use stainless steel monocoque "balloon" construction. The tanks are isogrid aluminum and are stable when unpressurized.[8]
  4. Use of aluminum, with a higher thermal conductivity than stainless steel, requires insulation for the liquid oxygen. The tanks are covered in a polyurethane-based layer.
  5. Accommodation points for parallel stages, both smaller solids and identical liquids, are built into first stage structures.[8]

The Atlas V was developed by Lockheed Martin Commercial Launch Services as part of the US Air Force Evolved Expendable Launch Vehicle (EELV) program. The term expendable launch vehicle means each vehicle is only used once. Launches are from Space Launch Complex 41 at Cape Canaveral Air Force Station and Space Launch Complex 3-E at Vandenberg Air Force Base. Lockheed Martin Commercial Launch Services continues to market the Atlas V to commercial customers worldwide.[9]

The first Atlas V was launched on August 21, 2002, and all subsequent launches have been successful except for the 2007 anomaly. The Atlas V family uses a single-stage Atlas main engine, the Russian RD-180 and the newly developed Common Core Booster (CCB) with up to five Aerojet made strap-on solid rocket boosters. The CCB is 12.5 ft (3.8 m) in diameter by 106.6 ft (32.5 m) long and uses 627,105 lb (284,450 kg) of liquid oxygen and RP-1 rocket fuel propellants. The booster operates for about four minutes, providing about 4 meganewtons (860,000 lbf) of thrust at start, the major part of this thrust, 4.152 meganewtons being provided by Russian RD-180 engine.[8] If strap-on solid fuel boosters are employed, each provides an additional 1.27 meganewtons (285,500 lbf) of thrust for 94 seconds.

The Centaur upper stage uses a pressure stabilized propellant tank design and cryogenic propellants. The Centaur stage for Atlas V is stretched 5.5 ft (1.68 m) relative to the Atlas IIAS Centaur and is powered by either one or two Aerojet Rocketdyne RL10A-4-2 engines, each engine developing a thrust of 99.2 kN (22,300 lbf). The inertial navigation unit (INU) located on the Centaur provides guidance and navigation for both the Atlas and Centaur, and controls both Atlas and Centaur tank pressures and propellant use. The Centaur engines are capable of multiple in-space starts, making possible insertion into low Earth parking orbit, followed by a coast period and then insertion into GTO. A subsequent third burn following a multi-hour coast can permit direct injection of payloads into geostationary orbit.[10] As of 2006, the Centaur vehicle had the highest proportion of burnable propellant relative to total mass of any modern hydrogen upper stage and hence can deliver substantial payloads to a high energy state.[11]

Many systems on the Atlas V have been the subject of upgrade and enhancement both prior to the first Atlas V flight and since that time. Work on a new Fault Tolerant Inertial Navigation Unit (FTINU) started in 2001 to enhance mission reliability for Atlas vehicles by replacing the existing non-redundant navigation and computing equipment with a fault tolerant unit.[12][full citation needed] The upgraded FTINU first flew in 2005,[13][full citation needed] and in 2010 a follow-on order for more FTINU units was awarded.[14][full citation needed]

On February 24, 2012, Atlas V lifted its heaviest payload to date into orbit—a 15,000-pound (6,800 kg) military satellite - MUOS-1.[15]

2007 valve anomaly[edit]

The only anomalous event in the use of the Atlas V launch system occurred on June 15, 2007, when the engine in the Centaur upper stage of an Atlas V shut down early, leaving its payload – a pair of NRO L-30 ocean surveillance satellites – in a lower than intended orbit. The cause of the anomaly was traced to a leaky valve, which allowed fuel to leak during the coast between the first and second burns. The resulting lack of fuel caused the second burn to terminate 4 seconds early.[16] Replacing the valve led to a delay in the next Atlas V launch.[17]

GX rocket[edit]

The Atlas V Common Core Booster was to have been used as the first stage of the joint US-Japanese GX rocket, which was scheduled to make its maiden flight in 2012.[18] GX launches would have been from the Atlas V launch complex at Vandenberg AFB, SLC-3E.

In December 2009, the Japanese government decided to cancel the GX project.[19]

Cost[edit]

In 2013, the cost for an Atlas V 541 launch to GTO (including launch services, payload processing, launch vehicle integration mission, unique launch site ground support and tracking, data and telemetry services) was about $223 million (inflation adjusted $226 million in 2014).[20] In 2014 the ESA contracted ULA to launch the Solar Orbiter for around $173 million.[21] Since about 2005 Atlas V has not been cost-competitive for most commercial launches, where launch costs were about $100 million per satellite to GTO in 2013.[22]

Future developments[edit]

Atlas V CTS (Crew Transportation System)[edit]

As early as 2006, ULA's predecessor company Lockheed Martin was looking at a human-rated version of the Atlas V. An agreement between Lockheed and Bigelow Aerospace that year was reported that could lead to commercial private trips to low-Earth orbit (LEO).[23]

Beginning in 2010, ULA did design and simulation work to human-rate the Atlas V for carrying passengers. ULA won a 2010 small contract of US$6.7 million in the first phase of the NASA Commercial Crew Development Program (CCDev) to develop an Emergency Detection System (EDS) for human-rating the Atlas V launch vehicle.[24] As of February 2011, ULA "is still finishing up work on its $6.7-million award... In December ULA carried out a demonstration of its Emergency Detection System ... The company said it received an extension from NASA until April 2011 'to enable us to finish critical timing analyses tasks' for [the] fault coverage analysis work."[25]

NASA solicited proposals for CCDev phase 2 in October 2010, under which ULA made a proposal for funding to "finish designing a key safety system for potential commercial crew launches on its Atlas and Delta rocket fleet." While NASA's goal is to get astronauts to orbit by 2015, ULA President and CEO Michael Gass has stated "I think we need to stretch our goals to have commercial crew service operating by 2014" and has committed ULA to meet that schedule.[26] Other than the addition of the Emergency Detection System, no major changes are expected to the Atlas V rocket, but ground infrastructure modifications are planned. The most likely candidate for the human-rating is the 402 configuration, with dual RL10 engines on the Centaur upper stage and no solid rocket boosters.[26]

On July 18, 2011 NASA and ULA announced an agreement on the possibility of certifying the Atlas V to NASA's "human-rating" standards.[27] ULA will provide NASA with data on the Atlas V, while NASA will provide ULA with draft human certification requirements.[27] As of July 2011 Bigelow Aerospace is still considering the use of a human-rated Atlas V for carrying spaceflight participants to its private space station.[28] In 2011, Sierra Nevada Corporation (SNC) picked the Atlas V to be the booster for its still-under-development Dream Chaser crewed spacecraft.[29] The Dream Chaser is designed to be a crewed vertical-takeoff, horizontal-landing (VTHL) lifting-body spaceplane that will be placed into LEO by an Atlas V, and is a proposed CCDev ISS crew transport vehicle.[29]

On August 4, 2011 Boeing announced it would use the Atlas V as the initial launch vehicle for its CST-100 crewed spaceship, intended for both NASA-funded trips to the International Space Station, as well as private trips to the proposed Bigelow Commercial Space Station.[30][31] As of August 2011, a three-flight test program is projected to be completed by 2015, and potentially will certify the Atlas V/CST-100 combination for human-spaceflight operations.[31] The first flight is expected to include an Atlas V rocket integrated with an unpiloted CST-100 capsule, to launch from Cape Canaveral's LC-41 in early 2015 into LEO.[30] The second flight is scheduled to be an in-flight launch abort system demonstration in the middle of that year.[31] The test-flight phase is expected to culminate with a crewed mission at the end of 2015, carrying two Boeing test-pilot astronauts into LEO and returning them safely.[31] In August 2012, George Sowers, ULA's vice president for Human Launch Services, stated that if funded, the first manned flight of the Atlas V could occur by late 2015.[32]

Atlas V HLV[edit]

In 2006, ULA offered an Atlas V HLV (Heavy Lift Vehicle) option that would use three Common Core Booster (CCB) stages strapped together to lift a 29,400 kg (64,816 lb) payload to low Earth orbit.[1] Approximately 95% of the hardware required for the Atlas HLV has already been flown on the Atlas V single core vehicles.[citation needed]

A report, prepared by the RAND Corporation for the Office of the Secretary of Defense in 2006, stated that Lockheed Martin had decided not to develop an Atlas V heavy-lift vehicle (HLV).[33] The report recommended for the Air Force and the National Reconnaissance Office to "determine the necessity of an EELV heavy-lift variant, including development of an Atlas V Heavy", and to "resolve the RD-180 issue, including coproduction, Stockpile, or U.S. development of an RD-180 replacement."[34]

The lifting capability of the Atlas V HLV is roughly equivalent to the Delta IV Heavy.[citation needed] The latter utilizes RS-68 engines developed and produced domestically by Aerojet Rocketdyne.

As of February 2008, the Atlas V HLV configuration was available to customers 30 months from the date of order.[35][dated info]

Atlas Phase 2[edit]

With the merger of Boeing and Lockheed Martin space operations into United Launch Alliance, the Atlas V program gained access to the tooling and processes for 5-meter-diameter stages, used on Delta IV. At 5 meters, a stage can accept dual RD-180 engines.[clarification needed] The proposed heavy-lift vehicle is "Atlas Phase 2" or "PH2".[clarification needed] An Atlas V PH2-Heavy (three 5 m stages in parallel; six RD-180s) along with Shuttle-derived, Ares V and Ares V Lite, was considered as a possible heavy lifter for use in future space missions in the Augustine Report.[36] The Atlas PH2 HLV would launch a payload mass of approximately 70 metric tons into an orbit of 28.5 degree-inclination.[36]

Variants[edit]

Each Atlas V booster configuration has a three-digit designation that indicates the features of that configuration. The first digit shows the diameter (in meters) of the payload fairing, and always has a value of '4' or '5'. The second digit indicates the number of solid rocket boosters attached to the base of the rocket, and can range from '0' through '3' with the 4-meter fairing, and '0' through '5' with the 5-meter fairing. The third digit represents the number of engines on the Centaur stage, either '1' or '2'. For example, an Atlas V 552 has a 5-meter fairing, five solid rocket boosters, and two Centaur engines, whereas an Atlas V 431 has a 4-meter fairing, three solid rocket boosters, and a single Centaur engine.[37] As of 2014, only the single-engine Centaur (SEC) has been used, with the first launch using the dual-engine Centaur upper stage planned for November 2016, when an Atlas V 402 will carry the Sierra Nevada Dream Chaser vehicle for its first orbital test flight.[38]

The 4-meter fairing, originally designed for the Atlas II booster, comes in three different lengths, the original 9-meter high version, as well as fairings 10 meters (first flown on the AV-008/Astra 1KR launch) and 11 meters (seen on the AV-004/Inmarsat-4 F1 launch) high. Lockheed Martin had the 5.4-meter (4.57 meters usable) payload fairing for the Atlas V developed and built by RUAG Space (former Oerlikon Space[39][full citation needed]) in Switzerland.[not in citation given] The RUAG fairing uses carbon fiber composite construction, based on flight-proven hardware from the Ariane 5. Three configurations will be manufactured to support the Atlas V. The short (10-meter long) and medium (13-meter long) configurations will be used on the Atlas V 500 series. The 16-meter long configuration will be used on the Atlas V Heavy. The classic fairing covers only the payload, leaving the Centaur stage exposed to open air. The RUAG fairing encloses the Centaur stage as well as the payload.[40]
